How do I know this strut fits my truck cap or camper shell?

Confirm fit by matching your current strut's part number or by measuring ball-center to ball-center length and required force. The Vepagoo C16-33313 lists an extended length of 18.7 inches and a 40 lb force rating, and it uses a 10mm nylon ball socket connection common to many topper applications.

• Compare OEM or interchange numbers: C16-33313, C16-20651, SE187P40, Lift-O-Mat 025248/25248, TAG# 68272/51630
• Measure extended length (ball-to-ball): ~18.7 inches
• Confirm shaft connection: 10mm nylon ball socket
• Check application: truck cap, camper shell, Leer/ARE/Snugtop topper rear window

What performance can I expect from a 40 lb gas strut?

A 40 lb rating provides firm, reliable lift for medium-weight rear windows and hatches without being overly stiff to operate. Expect smooth opening, steady hold in the open position, and gentle, controlled closing to reduce slamming and wear on hinges and seals.

• Lift force: 40 pounds per strut for stable support
• Operation: smooth opening and consistent hold
• Durability: suitable for frequent use on truck caps and toppers
• Connection: secure nylon ball-socket reduces play at mounting points

How difficult is installation, and what tools do I need?

Installation is straightforward and typically takes 4–5 minutes per strut using only a screwdriver or small hand tools. The Vepagoo gas strut is intended as a direct swap into existing mounting points; no drilling or modification is usually necessary.

• Tools required: screwdriver or small wrench set
• Procedure: remove worn strut, snap new strut onto ball mounts
• Time: about 4–5 minutes per side for most installs
• Support: 12-month protection and expert customer help available

Are there any compatibility tips or precautions I should follow?

Always verify the OEM part number or measure your current strut before ordering to ensure correct fit and performance. Handle gas struts carefully—do not puncture or heat them—and install them in the correct orientation to maintain longevity and safe operation.

• Check OEM/interchange part numbers before purchase
• Install in the same orientation as the original strut
• Do not attempt to disassemble or puncture the strut
• Contact Vepagoo support for sizing or fit guidance
